Most Americans distrust the worldwide decisions of Europeans simply because you've cause TWO WORLD WARS.
Sorry, but you don't have a good track record and you're not paying for your own defense either.
The notion of humans able to redirect the earth's natural and unnatural climate change assumes too many variables and is scientifically narcissistic in that it is based on humans having this capability. That much is hardly known if not even believed. In testing a scientific theory, the law of science is to change one variable and see the results. This is not possible with Climate Change. There are MILLIONS of variables, since there are millions of organisms on this earth. There is no scientific way of proving our actions will have desired results. That doesn't mean we shouldn't try or continue to study it.
Once you introduce politics into science, it is no longer pure science and loses some and/or all of its credibility.
By the way, if you read all the political scientific predictions in the 1970s, you do realize we're all supposed to have run out of fossil fuel, and/or died from the ozone hole. Historical fact beats scientific predictions every time. Sorry.
